By now, I am sure you have done something about this. It would be good to hear about your healing process and choices. I had a frozen shoulder in 2013/14, shortly after my neuropathy began, along with other neurological health issues. I tried cortisone shots and PT for over a year, but my shoulder mobility and pain did not improve at all. I ended up having surgery, which improved my range of motion, but it took a couple more years of PT to get close to normal, then another couple of years of PT for the nerve pain to end and to regain full mobility.
